Business Insider is tracking 2026 job cuts at major employers including Meta, Amazon, Visa, Walmart, and more, as AI and broader economic conditions reshape workforces.
More than 40 companies have laid off employees so far in 2026, according to Business Insider’s article body, with cuts spanning tech, media, finance, and retail. The OG description notes layoffs have hit over 35 companies and names Meta, Walmart, and Visa among the employers affected. The key takeaway for readers is that this is not isolated to one sector; workforce reductions are appearing across several corners of the business landscape.
Some companies, including Block, Coinbase, and Standard Chartered, have cited artificial intelligence as a key reason for layoffs. The article also says Angi referenced “AI-driven efficiency improvements,” while Atlassian said it is investing in AI as it reshapes its workforce. A World Economic Forum survey cited by Business Insider found that 41% of companies worldwide expected to reduce workforces in the next five years because of AI, while jobs in big data, fintech, and AI were expected to double by 2030.
Business Insider reports that Target is shifting resources from its supply chain into stores as part of its new CEO’s turnaround strategy.

More than 100 other companies have filed legally mandated WARN notices about job cuts to come in 2026, according to WARN Tracker as cited by Business Insider.
